Abstract

Highly effective bimetallic catalysts based on monodispersed palladium sols for acetylene alcohols hydrogenation, carbon monoxide oxidation, complex purification of exhausts of IC engines have been synthesized firstly. We have estimated the dispersity of Pd-Cu particles and revealed regulations of bimetallic particles formation, the role of Pd-Cu clusters and effect of dispersity on catalytic activity.
